Microsoft Azure. Microsoft 365. Secure hybrid infrastructure. The platforms your organisation depends on — configured, secured, and managed by a trusted partner with over 40 years of enterprise IT experience.
The Configuration Gap
Most South African businesses already pay for Microsoft Azure and Microsoft 365 while maintaining important infrastructure on-premises. Yet the majority use a fraction of the capabilities available to them.
M365 security policies sit at defaults. Conditional access is not enforced. Azure resources are provisioned without cost controls. On-premises infrastructure runs on ageing hypervisors with escalating licence costs.
You are paying for enterprise capability. You are getting basic functionality.
OAS closes the configuration gap. We deploy, secure, and manage your cloud and on-premises infrastructure so you get full value from every rand spent.
Microsoft Azure
Azure is the only global hyperscaler with South African data centres. Your data stays in-country. Your workloads run on enterprise-grade infrastructure. POPIA compliance is built into the foundation.
South African Data Centres
- South Africa North (Johannesburg) — primary region with Availability Zones for high availability and fault tolerance
- South Africa West (Cape Town) — secondary region for disaster recovery and geographic redundancy
Local data centres mean your data never crosses South African borders. Data sovereignty is guaranteed by infrastructure, not by contract.
Azure Migration and Management
OAS manages the full lifecycle — assessment, planning, execution, and ongoing optimisation:
Workload assessment
evaluate on-premises applications for cloud readiness
Migration execution
lift-and-shift, re-platform, or modernise workloads on Azure SA infrastructure
Cost optimisation
right-size resources, implement reserved instances, and enforce spending controls
Ongoing management
monitoring, patching, security, and performance tuning
Hybrid Identity With Microsoft Entra
Most SA enterprises run hybrid environments — on-premises Active Directory synchronised with Microsoft Entra (formerly Azure AD). OAS configures conditional access, multi-factor authentication, privileged identity management, and device compliance policies. One identity. Secure access across on-premises and cloud.

Microsoft 365 — Properly Secured
OAS does not simply enable Microsoft 365. We configure it correctly from day one and manage it ongoing.
Most organisations use less than 30 percent of M365 capabilities. Email works. Teams works. SharePoint is half-configured. Security policies remain at defaults. Compliance features sit untouched.
OAS activates the full M365 security and productivity stack:
Conditional access policies
enforce device compliance, location restrictions, and risk-based access controls
Data loss prevention (DLP)
prevent sensitive data leaving your organisation via email, Teams, or SharePoint
Microsoft Defender suite
Defender for Endpoint, Office 365, Identity, and Cloud Apps — deployed and tuned, not left at factory settings
Compliance and retention
eDiscovery, audit logging, and retention policies configured for POPIA, FSCA, and PCI-DSS requirements
The M365 Audit
Already running Microsoft 365? OAS audits your current deployment and activates the security, compliance, and productivity features you are already paying for. Most organisations discover significant untapped value within their existing licences.
On-Premises and Hybrid Infrastructure
OAS designs and manages resilient infrastructure across on-premises data centres and Microsoft Azure. Architecture decisions are based on workload performance, regulatory requirements, operational resilience, and the platforms your organisation already supports.
Platform Assessment and Modernisation
We assess compute, storage, virtualisation, networking, and recovery requirements before recommending a target architecture. This creates a practical modernisation path without tying the solution to a product OAS does not offer.
Managed Hybrid Operations
OAS brings monitoring, identity, security, backup, and cost governance together across on-premises and Azure environments. Your internal team gets consistent visibility while OAS manages day-to-day optimisation and support.
Data Sovereignty and Hybrid Architecture
South African enterprises face a dual requirement: harness cloud scale while keeping sensitive data within national borders.
OAS designs hybrid architectures that address both needs:
Azure SA regions
for cloud workloads with guaranteed data residency
On-premises infrastructure
for workloads requiring physical control, low latency, or air-gapped environments
Microsoft Azure
for disaster recovery, geographic redundancy, and elastic capacity
Citrix DaaS
spanning on-premises and cloud from a single management plane
Every architecture decision considers POPIA, industry-specific regulations, and your organisation's risk posture.
